'SI- IINGLE-MACHINE.

Specification of Letters Patent No. 12,842,V dated May `8, `1 855.

To aZZwZtom; it may concern: i

Be it known `that I, ANDREW P. WILSON, of Piqua, in the county of Miami and State of Ohio, haveinvented an Improvement in 5 the Machinefor Cutting Shingles; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to theletters of reference marked thereon.

To enable others skilled in the art to make and use my improvement, I will proceed to describe itsconstruction and operation.

, The machine is constructed as represented in the` accompanying drawing. The letters a, a, a, c, representing the side beams of the frame, j, g, cross'pleces or ties on'the underor lower side of the beams,

c, c and Z2, Z), cross pieces or ties on the upper side of the beams, constituting the framework of the machine. On the inside of each of the side beams are iron slides f, fixed permanently to the beams, on which is to work the gate (z', z", i, l,) containing the knife (e). The machine isto be placed .in a horizontalposition.

I y. The frame of the gate is constructed in the usual manner, as represented in Figure 2, of the drawing. The jaws of the gate (s, s, s', s) are of iron, and to project beyond the sidesfof `the gate a distance equal to the they are to work, thus holding the lgate firmlyon the iron slides, within the beams edges, is flat on the `upper side, with the proper thickness on the lower side in the center'to insure strength, tapering with a gradual bevel to each edge, and is placed in the center of the gate.V The doors (t, t,) as `represented in Fig. 2 extendfrom the inside of each end of the gate, to within a short dis- Z i tance of each edge ofthe knife (e) `and are u supported by slats underneath, `which are ufastened to the sidesrof the frame of the gate,` as represented by g, g, g, g, in Fig. 4 y by means of bolts or` screws whichlpass `through long holes :in the' slats.

` On the upper `side of the doors (t, 15,Fi`g.

f2) are placed slats Z, Z,Z, Z, running from` the ends of the gate toward theknife for `the purposeof supporting the block as hereafter described.

On the under side of the doors (ZJ, Fig. 3) are springs (m, m, m, m,) extending a `short distance under the knife for the pur- `pose of supporting the shingle while itis `1 when it will rest on the knife (e of the frame.` The knife (e) which has two ythe block to be cut, is in the center of the frame (a, a, a, a., Fig. l) between the cross ties (b, 5,) as represented by o, n, o. The

box is to be of sufficient size to admit any sized block that is to be cut. The inside of the box is to be faced with some kind of metal, to prevent wearing.

On the under side of the cross ties c, c, Fig. l, are attached cleaners (g, 9,) (see Fig. 5) extending from the ties toward the knife and reaching down to the doors (t, t,) with grooves (see Fig. 6) for the slats Z, Z, Z, Z, to pass backward and forward with the working of the gate. The doors (t t) are regulated by means of the long holes in the slats (g, g, g, g', Fig. 4) underneath; thus lowering one end of one door and elevating the other end, to` give the shingle the desired thickness and taper. 'i

The other door, on the opposite side of the knife `is regulated by the same means, as the first; but the end of the door of the first, that was elevated, to form the top of the shingle, inthe second is lowered to form the butt or thick end. And the en'd of the first door that was lowered to form the butt of thevshingle in the second is elevated to form the top. Place the block, out of which the shingles are to be cut, in the box 0, n, o, Fig.

. The power, which may be of any kind in use for propelling machinery, is attached to either end of the gate, by means of a pitman or shaft.

Draw the gate to one end of the slides f, f) when the block in the box 0, a, o', will fall `on the slats Z, Z, on the door U); the

door having been first regulated to form the `1The knife commences cutting the shingle,

which passes under the knife, and is supported by the springs m, m, Fig. 3, until the knife' passes under the cross tie Z), and

over the cleaner (g) which cleans the shingle from between the knife and springs, the

knife having passed under the tie Z) permits the block again to fall upon the slats on the door t on the opposite side of the knife.

The gate in passing back again brings the knife in contact with the block again, which ilo having fallen on the door opposite to the first reverses the new shingle to be out, taking the butt of the second shingle from the end of the block from which the top of the rst was taken; so on alternately. The knife having two edges, outs two shingles at each revolution of the wheel.

Vhat I claim as my invention, and desire to secure by Letters Patent, isf The mode of adjusting the block out of which the shingles are to be Cut, as set forth in the above specification, by means of the adjusting slats (g, g, g, g, Fig. 4) underneath the doors, (t t) and also the springs for support-ing the s ingle, as set forth above; also thel cleaners (g, g,) for the purpose of cleaning the shingle from between the knife and springs and for the purpose of keeping the doors (t, L) clean from all substance that may fall on thenn.
